Ignition Problems STILL

[lodder]

Hey, I'm still trying to find out what the problem is with my car! From idle to 3500, it sounds like it's miss firing, like a hesitation. It only throws an ignition signal code (21). I have a brand new engine harness and noticed that there is a ground wire coming out of the harness with the boost selonoid harnesses right near the 4 pin plug for the ignitor chip. I had a look on mine and noticed that there is no ground there. Does any one know if this ground is part of the ignition? Or is it part of the boost selonoid. I've changed the coil plugs and checked for continuity. I've tried another ignitor chip and checked for continuity there too. Just a shot out of the dark, would this have any thing to do with the speed sensor?


Also has anyone successfully mated a SR bell housing to a KA rear half? Because that is what I'm running at the moment. It's not bad but I think that the clutch needs a little adjusting.

Thanks.
